Problems solved by technology

(3) Breeding new taro species with seed seeds may result in a large number of omissions due to the small size of the taro species.
Deficiency of the present invention is (1) mentions in the method three months and just can breed the konjac miniature seed taro of 1.5 grams, but the required period of early stage tissue culture is longer to seedling height 4-5cm from callus tissue to bud differentiation , generally takes 3-6 months
(3) The cost of using tissue culture is relatively high

Abstract

The invention discloses a fast breeding method of konjak seeds obtained from sexual reproduction. The fast breeding method comprises (1) selecting konjak true seeds, (2) carrying out stratification freezing treatment on the seeds, (3) carrying out high temperature treatment on the seeds for 24h, (4) immersing the seeds, covering the seeds with a cover, carrying out moisturizing and transplanting the seeds into a water culture tank after the seeds produce buds, (5) preparing a nutrient solution of which the concentration is 1 / 5 that of the garden standard formula solution, (6) putting the prepared nutrient solution into the water culture tank, simultaneously, transplanting the germinal seeds into the water culture tank and fixing the germinal seeds to a colonization plate, (7) checking the EC value and the pH value of the nutrient solution in the water culture tank once every 2-6 days and adjusting the EC value and the pH value in an appropriate range, (8) controlling the environment temperature of the water culture tank in a range of 25-35 DEG C and humidity in a range of 60-70 degrees, and (9) after 90 days, taking out the small bulbs of the konjak seeds, airing the small bulbs and preserving the small bulbs as konjak tuber seeds for sowing. The method can fast breed konjak seeds.

Description

technical field [0001] The invention relates to the technical field related to seed cultivation, in particular to a method for rapid breeding of konjac seeds. Background technique [0002] The seed of konjac is the result of natural or artificial pollination after konjac flowering, so as to obtain the sexual organs of konjac. The growth process of konjac seeds is the process in which konjac seeds go dormant for a long time after they mature, germinate seedlings, and finally form small bulbs. [0003] The way of konjac propagation mainly adopts its bulbs and rhizomes and other asexual reproduction methods. The main problem is that konjac has been asexually propagated for a long time, and its provenance is relatively single, which makes its offspring easy to accumulate diseases and degrades very seriously, which directly affects the yield and quality of konjac. The use of konjac seeds for propagation can not only exert heterosis, enhance disease resistance, increase the repr...
